Split message initiated payment system, method and apparatus

ABSTRACT

A system, method, and computer-readable storage medium configured to split a payment card transaction into separate channels with a merchant bill message and cardholder payment message.

BACKGROUND Field of the Disclosure

Aspects of the disclosure relate in general to security and fraud prevention in financial services. Aspects include an apparatus, system, method and computer-readable storage medium to split a payment card transaction into separate channels with a merchant bill message and a cardholder payment message.

Description of the Related Art

In modern times, payment cards are rapidly replacing cash to facilitate payments or other forms of financial transactions. A payment card is a card that can be used by a cardholder and accepted by a vendor or merchant to make a payment for a purchase or in payment of some other obligation. An example of a payment card includes a stored-value card (such as a transit card or gift card), credit card, debit card, automated teller machine card, or charge card. The payment card is generally used to pay an exact amount.

Payment cards are affiliated with payment networks, which are operational networks that enable monetary exchange between parties.

Typically during a purchase transaction, payment card information is captured at a merchant point-of-sale (POS) device, and transmitted over a single channel to a payment card issuer financial institution for transaction authorization via an acquiring financial institution and the payment network. If the issuer deems the payment cardholder credit worthy and that the transaction is unlikely to be fraudulent, the issuer notifies the payment network that the transaction is authorized. This authorization is sent to the merchant POS device via the acquirer, and the transaction is concluded.

SUMMARY

Embodiments include an apparatus, method and computer-readable medium configured to split a payment card transaction into separate channels with a merchant bill message and cardholder payment message.

In a point-of-sale terminal method, a processor generates a bill for a purchase transaction. The processor generates a purchase transaction code, the purchase transaction code based at least in part on an identifier for the merchant or point-of-sale terminal, transaction amount, and date/time of the transaction. A display or printer visually presents a representation of the purchase transaction code on a display or printer. A network interface transmits a merchant bill message to a payment network. The merchant bill message containing the purchase transaction code and not containing customer payment information. The network interface receives a transaction approval or decline message.

In a customer payment device method, a customer payment device receives a purchase transaction code from a point-of-sale terminal. The purchase transaction code includes a representation of a bill for a purchase transaction, an identifier for the merchant or the point-of-sale terminal, transaction amount, and date/time of the purchase transaction. A processor extracts the bill for the purchase transaction from the purchase transaction code. A display prompts a customer to approve the bill for the purchase transaction. The processor authenticates a customer approval of the bill for the purchase transaction. Customer payment information is retrieved from a database. The network interface transmits a cardholder payment message to an issuer. The cardholder payment message including the purchase transaction code and the customer payment information.

In a payment network method, a network interface receives a merchant bill message from a merchant. The merchant bill message contains a purchase transaction code and does not containing customer payment information. The network interface receives a cardholder payment message from a cardholder payment device. The cardholder payment message includes the purchase transaction code and customer payment information. A processor matches the merchant bill message with the cardholder payment message based at least in part on the purchase transaction code. The processor combines the merchant bill message and the cardholder payment message into a single transaction message. The network interface transmits the single transaction message to an issuer for approval.

DETAILED DESCRIPTION

One aspect of the disclosure includes the realization that hacking into merchant computers has resulted in the theft of millions of customer payment card account numbers.

Yet another aspect of the disclosure is the realization the damage caused by hacking may be obviated by preventing merchant computers from having customer payment card account numbers in the first place.

Another aspect of the disclosure is the understanding that by splitting a payment transaction into two separate messages that are transmitted via separate channels would allow a merchant to be paid without providing the merchant the customer's payment card information. In such an aspect, the two separate messages may be a merchant bill message (which does not contain payment information) and a cardholder payment message.

Embodiments of the present disclosure include a system, apparatus, method, and computer-readable storage medium configured to split a payment card transaction into separate channels with a merchant bill message and cardholder payment message.

It is understood by those familiar with the art that the term “payment card” includes credit cards, debit cards, charge cards, and Automated Teller Machine (ATM) cards. In addition to payment cards, it is understood by those familiar with the art that the embodiments described herein apply equally to payments via mobile devices (such as augmented reality devices, key fobs, mobile phones, tablet computers, and the like), electronic wallets, virtual payment cards, cloud-based payment devices, cashless payment devices/methods, or computers.

In the following description, the terms “customer” and “cardholder” may be used interchangeably. In most of the embodiments described below, customers will be paying with payment cards. However some in embodiments, customers may also electronically pay for a purchase transactions using checking accounts.

Embodiments will now be disclosed with reference to an exemplary embodiment of system 1000 of FIG. 1 configured to split a payment card transaction into separate channels with a merchant bill message and cardholder payment message, constructed and operative in accordance with an embodiment of the present disclosure. In such a payment transaction, splitting the transaction into separate billing and payment messages allow the payment transaction to occur without presenting the payment information to the merchant.

In system 1000, a financial institution called the “issuer” 1400 issues a payment card to a cardholder, who uses the customer payment device 2000 to tender payment for a service or good at a merchant 1200. The merchant 1200 has a merchant point-of-sale device 5000 which administers the sale on behalf of the merchant.

The merchant 1200 is affiliated with a financial institution. This financial institution is usually called the “acquiring bank,” “merchant bank” or “acquirer” 1300. At the point of payment, merchant point-of-sale device 5000 does not capture any payment card information, such as a Primary Account Number (PAN) or any other payment information. Instead, merchant point-of-sale device 5000 sends a merchant bill message to an acquirer 1300. The acquirer 1300 in turn forwards the purchase transaction details to a split message matching switch 4200 at a payment network 4000.

Payment network 4000 processes payment transactions. For sake of example only, the present disclosure will describe a payment network-based system, such as the payment system using the MasterCard® interchange, Cirrus® network, or Maestro®. The MasterCard interchange is a proprietary communications standard promulgated by MasterCard International Incorporated for the exchange of financial transaction data between financial institutions that are customers of MasterCard International Incorporated. Cirrus is a worldwide interbank network operated by MasterCard International Incorporated linking debit and payment cards to a network of ATMs throughout the world. Maestro is a multi-national debit card service owned by MasterCard International Incorporated.

Simultaneously, the merchant point-of-sale device 5000 presents the customer a payment transaction code that encapsulates the merchant bill message or details of the transaction. In some embodiments, the payment transaction code is an encoded representation of a merchant bill message or details of the transaction. The payment transaction code is described in greater detail below.

In some embodiments, the customer manually enters the payment transaction code into a customer payment device 2000; in other embodiments, the customer payment device 2000 scans the code optically or otherwise receives the code from the merchant point-of-sale device 5000.

When the payment transaction code is entered into the customer payment device 2000, the customer is presented options of how to electronically pay for the transaction. For the sake of example, the customer decides to pay with virtual payment card information stored within the customer payment device 2000.

The customer authorizes payment of the transaction using the customer payment device 2000, which electronically routes the payment information, along with the associated payment transaction code, to an internet payments gateway 4100 at the payment network 4000. Using the payment transaction code transmitted in each message, the split message matching switch 4200 matches the merchant bill message with the cardholder payment message, combining both parts of the transaction into a single message transmitted by a network switch 4300 to the issuer 1400 financial institution.

The issuer 1400 then either authorizes or declines the transaction, and the result is reported to the merchant 1200.

Embodiments will now be disclosed with reference to an exemplary embodiment of customer payment device 2000 of FIG. 2, configured to split a payment card transaction into separate channels with a cardholder payment message, constructed and operative in accordance with an embodiment of the present disclosure.
